本篇文章为大家展示了如何在HTTP协议接口测试中使用HttpClient,内容简明扼要并且容易理解,绝对能使你眼前一亮,通过这篇文章的详细介绍希望你能有所收获。
一、GET请求: GET请求时,参数一般是写在链接上的,代码如下:
public void get(String url){ CloseableHttpClient httpClient = null; HttpGet httpGet = null; try { httpClient = HttpClients.createDefault(); RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build(); httpGet = new HttpGet(url); httpGet.setConfig(requestConfig); CloseableHttpResponse response = httpClient.execute(httpGet); HttpEntity httpEntity = response.getEntity(); System.out.println(EntityUtils.toString(httpEntity,"utf-8")); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { if(httpGet!=null){ httpGet.releaseConnection(); } if(httpClient!=null){ httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } }
如果想把参数不写在链接上,单独的传进去,则可以这样:
public void get(String url, Map<String, String> params){ CloseableHttpClient httpClient = null; HttpGet httpGet = null; try { httpClient = HttpClients.createDefault(); RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build(); String ps = ""; for (String pKey : params.keySet()) { if(!"".equals(ps)){ ps = ps + "&"; } ps = pKey+"="+params.get(pKey); } if(!"".equals(ps)){ url = url + "?" + ps; } httpGet = new HttpGet(url); httpGet.setConfig(requestConfig); CloseableHttpResponse response = httpClient.execute(httpGet); HttpEntity httpEntity = response.getEntity(); System.out.println(EntityUtils.toString(httpEntity,"utf-8")); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { if(httpGet!=null){ httpGet.releaseConnection(); } if(httpClient!=null){ httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } }
二、POST请求的表单提交方式,代码如下:
public void post(String url, Map<String, String> params){ CloseableHttpClient httpClient = null; HttpPost httpPost = null; try { httpClient = HttpClients.createDefault(); RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build(); httpPost = new HttpPost(url); httpPost.setConfig(requestConfig); List<NameValuePair> ps = new ArrayList<NameValuePair>(); for (String pKey : params.keySet()) { ps.add(new BasicNameValuePair(pKey, params.get(pKey))); } httpPost.setEntity(new UrlEncodedFormEntity(ps)); CloseableHttpResponse response = httpClient.execute(httpPost); HttpEntity httpEntity = response.getEntity(); System.out.println(EntityUtils.toString(httpEntity,"utf-8")); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { if(httpPost!=null){ httpPost.releaseConnection(); } if(httpClient!=null){ httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } }
三、 POST请求的RAW参数传递:
public void post(String url, String body){ CloseableHttpClient httpClient = null; HttpPost httpPost = null; try { httpClient = HttpClients.createDefault(); RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build(); httpPost = new HttpPost(url); httpPost.setConfig(requestConfig); httpPost.setEntity(new StringEntity(body)); CloseableHttpResponse response = httpClient.execute(httpPost); HttpEntity httpEntity = response.getEntity(); System.out.println(EntityUtils.toString(httpEntity,"utf-8")); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ try { if(httpPost!=null){ httpPost.releaseConnection(); } if(httpClient!=null){ httpClient.close(); } } catch (IOException e) { e.printStackTrace(); } } }
